In the upper-left tree, double-click a port.

Double-click

, which is displayed below the specified port.

Check to see if all the WWNs of the host bus adapters to be controlled by

using Server Priority Manager appear below

Monitor

If some of the WWNs are missing, use the procedure in Monitoring All

Traffic between HBAs and Ports to move all WWNs to below

Monitor

Click

Monitor

to display the information of the host bus adapters that are

monitored in the list on the right of the tree.

Right-click a host bus adapter (WWN) in the list and then select

Non-Prio

->> Prio

from the pop-up menu.

The

Attribute

column of the selected WWN in the list displays

Prio

. If you

want to specify more than one prioritized WWN, repeat this operation.

Note:

You cannot change the priority of a WWN which is contained in an

SPM group. For details on how to change the attribute of a WWN contained

in an SPM group, see Switching Priority of an SPM Group.

Right-click a host bus adapter (WWN) in the list and then select

Prio ->>

Non-Prio

from the pop-up menu.

The

Attribute

column of the selected WWN in the list displays

Non-Prio

If you want to specify more than one non-prioritized WWN, repeat this
operation.

Note:

You cannot change the priority of a WWN which is contained in an

SPM group. For details on how to change the attribute of a WWN contained
in an SPM group, see Switching Priority of an SPM Group.

You must set upper limit values for the

Non-prio.

specified ports. For

details, see Setting Upper-Limit Values for Non-Prioritized WWNs.

10.

Repeat steps 4 to 9 for ports (except for the port selected in step 9).
If one host bus adapter is connected to multiple ports and you specify the

priority of the host bus adapter for one port, the specified priority will be

also applied to the host bus adapter settings for other connected ports
automatically.

11.

Click

Apply

in the

Server Priority Manager

window.

The settings on the window are applied to the storage system.

Follow the instructions in Starting and Stopping Storage System Monitoring to

measure traffic (i.e.. I/O rates and transfer rates).
